NEEWHAM is a random word made to throw people off in mid-conversation. It has no real definition, though in some cases can be used as a battle cry meaning, "I'm going to rape every single one of you and rip off your fingers and cram them down your throat. then i'm going to take off your leg and shuv it straight up your ass. I'l nail one of your balls to the ceiling and one to the wall and make you dance on a hot bed of nails while singing 'twinkle, twinkle, little star' as i whip you with your own intestines and make you bleed out of your eyes."
